B has to be 70° and A has to be 115° so I’m confused by your options
Answer:

Step-by-step explanation:
The given quadratic equation is:

Comparing it with the standard form of Quadratic Equation
, we get:
a = 3, b = -9 and c = 1
Discriminant = b² - 4ac
D = (-9)²-4(3)(1)
D = 81 - 12
D = 69
Answer:
B) Scalene Triangle
Step-by-step explanation:
This must be a scalene triangle because:
If it were a right triangle, there would be a right angle so A is out
If it were an equilateral triangle, all 3 angles would be equal to each other so C is out
If it were an isosceles triangle, 2 angles would be equal to each other so D is out
A scalene triangle consists of angles that add up to 180 degrees, but none of them are equal to each other. Therefore B is right.
